SPECIFICATION forming part of Letters Patent No. 455,719, dated July 7, 1891. Application filed September 1'7, 1890- firial No. 365,277. (No model.) i

To all whom it may concern:

Be it known that L'SAMUEL G. HURLBUT, a citizen of the United States, residing at Elmwood, in the county of Hartford and State of 5 Connecticut, have invented new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

The object of this invention in type-writers is the production of a machine which is sim- IO ple and inexpensive, easy of manipulation, and not likely to become-deranged orimpaired ,uhder protracted use; and the invention consistsin the construction and combination of parts, substantially as will hereinafter more Reference is to be had to the accompanying drawings, forming part of this specification, A in which- Figure 1 is an elevation at one side of the 2 machine, certain of the parts being broken away for clearer illustration. Fig. 2 is a sectional elevation of the machine, taken on the line 2 2, Fig. 1. Fig. 3 is a plan view. Fig. 4 is. an elevation of portions of the machine 25 as seen at the side opposite that shown in Fig.1. Fig. 5 is a view in elevation of some of the parts shown in Fig. 4, but occupyingditferent positions as ensues in the operation -of the machine; and Figs. 6, 7, and 8 are enlarged perspective views of portions of the propulsion devices for the machine, shown in elevation in Figs. 4-and 5, '2t-Ild;WhlCh will {be hereinafter more fully described. Fig. 9 is a vertical sectional view of a portion of the machine, taken centrally thereof on the plane indicated by line 9 9 in Figs. 2- and 3. Fig. 10 is a sectional view in illustration of a cerv tain construct-ion hereinafter referred to.

The frame A of the machine is to be of any suitable form and design to most efficiently support the operative mechanism, and, as shown, comprises legs or standards a a, horizontal bed I), and a horizontal bearing d for the horizontal shaft 0, which is rotatable in said bearing, and from which horizontal bearing 1 theelevated platform 6 is supported. The bed I) has parallel ways f f, extending from front to rear thereof, on which a carriage B is movable, said carriage in turn hav- 50 ing waysg theucin at right angles tQthe ways fully appear, and be set forth in the claims.

pressiomface of f, in which latter ways slides a carriage C,

which constitutesthe platen, and slightly above said platen is the normal position of an under peripheral portion of the type-drum D, which is mounted on said shaft 0, to rotate therewith.

The type-drum D embodies the rim h,'in which two sets of type are arranged, an upper-case set circularly arranged around one side of the rim, and a lower=case set also circularly arranged around the rim at its other side. Similar or corresponding characters of the upper and lower case sets are paired with each other-thatis, the-type bearing a capital is in a line on the rim parallel with the axis thereof which passes through the type bearing the same letter in'the lowercase style of type, while the numerals may be paired with punctuation-marks or other characters which it is desirable to have comprised within the printing capacity ofthe ma-. chine. Each type of both the upper and lower case sets is radially movable on. and withv relation to the rim of the drum, each of said 1 types consisting of' a head 10, bearing theimthe respective characten-a spindle portion 12, and afoot or lug 13-on-its I inner extremity, betweenwhich and thef-inner periphery of the'rim is applied "a spring.

14 for maintaining the said type initsinner most disposition shown. The shaft c, on

whichthe drum is mounted, has a beveled gear '11 thereon, with which engages the bevel-gear jon the vertical shaft is, which is mounted to rotate, but is fixed against vertical movement.

There is a dial E at the upper-end portion of the shaft k, above which is a handle-knob l, and said knob is freely movable vertically with relation to the said shaft, the downward movement of the knob forcing downwardly the said dial, (which is constrained against rotation,) although there is between the knob and the shaft such an engagement that as the knob is turned a corresponding rotational 9= movement will be also impartedto the shaft.

The construction last referred to is parti'cularly illustrated in the .sectionalview, Fig. ,9, and, as shown, on the upper end of the shaft I k is keyed or otherwise secured a block rm, rco

which forms in substance a splined connection between the knob Z, which is hollow, and the shaft is. The dial is necessarily centrally apertured, as at 15, whereby as the 5 knob is rotated, and with it the block m, a portion of the depth or thickness of which is normally in the plane of the dial, there will be no tendency to rotate the dial, or by the dial there will be no obstruction to the rota- IO- tion of the knob, block, and shaft. The dial has a representation of characters thereon corresponding to or in the same succession as those on the type-drum, all so that as the knob is turned and the index-pointer o is op- I 5 posite a certain character on the dial the corresponding character onthedrum is at the lowermost or printing position-that is, ,in-

a line projected vertically through the axis of the drum. 1 M

It will be noticed, Fig. 1, that the dial E is carried on the upper ends of the vertical posts 19 p of a frame F, which is vertically movable relatively to the drum and the platform 6, being guided in vertical bearings of the latter, and after the knob and shaft have been turned, rotating the drum to present the proper character at the printing'position, the knob and dial are then pressed downwardly, the said frame F in its downward movement effecting the impact of the selected type against the platen or paper or card thereon through the hearing by the downward projection q of the frame F upon thelever r, pivoted on the frame A, to swing in a vertical plane, and normally standin g by a vertically-offset extension 19 at its end opposite the pivot, just above the surface of the top of the type of one of the pair thereof which is in the printing position. There is fixed on the rotatable shaft 0, carrying the type-drum, a plate G, having radial slots 8 therein, with particular ones, of which a centering or locking post If, vertically fixed on and extending below the'dial, engages at each depression with the upper portion or the mechanism described for elfecting the printing, and said slots 5 are in arrangement relative to the movable type, substantially as shown in Fig. 1that is, .there is a slot 8 for each type pair comprised in the drum--and the working-slot for each type is across the drum therefrom in a plane projected through the center of the type and the drum-axis. Thus for the type in the printing position, or s is then the drum-centering slot. The outer walls of said slots near the borders of the plate are in V arrangement, as shown, whereby the adjustment of the drum may be more readily insured.

Assuming that the drum and other parts movable therewith are in the positions shown in Figs. 2 and 3 for printing from the lowercase set of type and it is desired to imprint by certain type of the upper-case series, the same is performed and permitted as and through mechanism next described and explained.

- The elevated platform e is supported on ported and steadied by the hanger z, in the lower extremity of which the outer end of the shaft 0 is supported.

H represents a latch-lever intermediately pivotally hung under the platform upon the hanger w, at the outer end of which it is provided with a latehing lug 25, which takes into one or the other of two notches 26 of a member 27 of the upright a, while-the inner end of said lever H lies under and supports a sleeve 28, which loosely encircles the vertical shaft is, and which also is free to move vertically withrelation to the platform 6. The lever H is held in its latching engagement with the member 27 and to su the said sleeve 28 by the spring 29, Fig.2. A spindle 30 plays loosely through a vertical hole therefor in the block m, before mentioned, and is provided at its upper end with a key'or finger-piece 32, which is within the hollow knob Z, the opening in said knob extending to the top thereof. By pressing downwardly on the finger-key 32 the same is caused to force the sleeve 28 downwardly and depress the adjacent end of the lever H, the other end of said lever swinging out of latch with one of the notches of the member 27, and the force being suitably applied in the direction of the axis of shaftc, the platform e, with the shaft is, and the drum-shaft and drum, and the frame f, with the dial and handle-knob, may be all bodily moved horizontally fora distance corresponding to that between the centers of the upper and lower case type series, the shaft 0 telescoping within the sleevebearing (1, and under the operation above described the hammer-extension 19 of the lever 1- occupies a working position then over a type aligned for printing'of the series of the other case.

The mechanism for insuring a step-by-step movement ofthe platen at each depression of the printing or type-operating mechanism, as above described, will be now set forth.

There is horizontally mounted under the bed, parallel with the shaft c,ashaft J, which is adapted to .move longitudinally in one of its bearings 35, which is on the frame A, the other bearing 36 for supporting said'shaft being constituted by a hanger 37, secured on the carriage B. Upon the inner end of said shaft J is secured a barrel 38, which is encircled by the tension-strap 39, the extremities 40 and 41 of which-are extended and secured to 'difierent ends of the platen C, so that anymotion of the shaft J will impart pport IIO the next depression of said plate'L, as'has through the medium of said barrel and strap a movement of the platen at right angles to the axis of the shaft J. There is in substance upon the outer portion of said shafta disk K, having in regular and circular arrangement on and extending from the face thereof the series of pins 43. L represents a plate which is adapted to slide in ways 45 on the end of the frame A for a reciprocating motion radially with relation to the axis of the said shaft J and disk K thereon. The said plate has within its front side a way 46,which is in a radial line drawn from the axis of shaft J through one of the pins 43 adjacent said plate L, one side of said way being open, as

, shown at 47, to permit the admission thereinto of thepins 43 one after the other, and

there is another way 48 in the face of said plate L, which with relation to the normal position of said plate (shown in Fig. 4) extends from a .point 49 on the edge of said plate, which is adjacent the circle of arrangement of the pins 43 angular-1y with relation to and merges into the said radial way 46. A pawl 50 (shown in detail in Fig. 8) lies within the said way 46, and comprises a spring-shank 52, by which the pawl is secured to the base of i s way inside oft-he circle of arrangement of the pins 43, and outside of said circle of arrangement said pawl is inclined forwardly relative to the depth of its way, as at 53,

- and also has its end inclined, as at 54, to

conform with one side wall of the angularlydisposed way 48. I There is lying in and along the said way 48 a similarlyformed pawl 55, having a spring-shank, and each of said pawls at its enlarged and working extremity is normally sprung outwardly some little distance from the base of the way within which it is located, this relation being particularly seen in Fig. 6. Now it will be plain thatif a particular pin of the Sc ries 43 is to be brought opposite the spring shank of the pawl 50,-as indicated by 43, Figs. 4 and 6, and the plate L is forced radially toward the center. of the disk-K a suit able distance, and the proximity of the end of said pin with the said'pawl is such that an impingement between .the pin and pawl is had, the pawl as it moves downwardly with the plate L will be forced inwardly until its end 54. has passed below th'e said pin, when the pawl will spring outwardly again to act as a detent against the passage of said way '46 back again over the pin, the pin then standing in line with. the angular way 48, as indicated in Fig. 5. 'On the then upward movement of the plate L the side of the way.48 acts as an inclined plane against the pin 43, and by the time theplate L has resumed its normal position the said pin on the disk has been moved aidistance equal tothat between apair of said pins,and the one next behindthe pin -43 has now been brought into the line of the said way 46 to' be acted uponon already been described. The reciprocatory motion of the said plateLis through the connection ofthe link 60,which is secured atits upper end with the radial arm or lever 62, which, is affixed on a rock-shaft 63,.and which receives its rock through the engagement with the radial arm 64 thereof of a foot 65, which is secured at the lower portion of the said vertically-movable frame F.

The bearing for the shaft J, which is supported in the frame Ain order that said shaft may at times have an axial movement and without altering the position of the disk K, consists of a sleeve, on the outside of which the hub of the disk K is keyed, and axially outside of said hub said sleeve is kerfed or slitted, whereby it is capable as to such extremity of a radial deflection, and such extremity being tapered and externally'screwthreaded, as at 66, and'receiving the tighten-. ing-nnt 67, the engagement between the shaft moving the shaft axially the bed B will be correspondingly moved, carrying therewith the platen in a direction across the printingline thereof, and thus the spacing between lines ofprinting maybe re'adilyeife'cted withoutmoving the paper or card on the platen. I have indicated in the drawings atMan inking-ribbon and supporting appliances therefor properly in relation to the face of the type. Other inking contrivances may be substituted for this, however, if desired.
